Description:A huge demonstration in the Syrian city of Aleppo in support of President Bashar al-Assad. These pictures - aired by Syrian television - show large crowds chanting and drumming, with a podium for speakers to address the rally. The pro-Assad demonstration is also to thank Russia and China for blocking European-led efforts to impose sanctions on the Syrian government. The decision by Moscow and Beijing to use their veto power drew condemnation from the United States and its Western allies.(0:48)
